Application filed July 30, 1914. Serial No. 854,153.

To all whom it may concern 1 Be it known that l, Friars TrmDsnN, a

citizen of theUnite'd States; residing at Dike, in the countyot' Grundy and State of Iowa have invented certain new and useful: Improvements in Rocking-Chair Attachments, of which the following is a specification.

This invention appertains to rocking chair attachments for automatically supplying a practically constant current of air for the occupant of said chair during roclc ing movement and my main object is to provide simple manipulating means whereby the air supplying member or members may be rendered operative and inoperative at will when the chair is used. To this end I employ a pair of bellows attached tothe chair and having air discharging conduits" arranged to direct the air against the occupant of the chair in combination with looking members adapted to engage the bellows upon manipulation of an operating member so as to hold each bellows element compressed and inoperative when the air supply is not desired.

A further object in view is to provide ad-- just-able connections intermediate the attachment and the chair structure so as to enable the invention to be connected to vari- 30 a vertical sectional view on the line 3-3 of Fig. 2 through my attachment. Fig. 4 is a perspective View of the attachment and showing more'clearly'the bellows members locked in inoperative position. Fig. 5 is a detail sectional view on the line 5-5 of'Fig.

Describing the embodiment of my inven tion and referring to the drawings, the nu meral 1 designates a rocking chair of conventional type beneath the seat of which my attachment is adapted to be secured. As

chairs of this character varyin size'and partlcularly with reference to the width at the front and rear portions, it is desirableto .Li. I

employadjustable attaching means intermediate the attachi'nent hereinafter to be mor particularly described and the chair structure; This means consists of angular shaped brackets 2 one oi which is secured to each leg by screws or other fastening members 3 passing through one arm of said-bracket,- the other or horizontal arm of the bracket projecting inwardly and extending tl'irougli, a keeper isecured in any desired manner to themain plate or board 5 of a double bellows. The lreepert is provided with a set" screw (5 which is provided toiliold the last mentioned arm of the bracket 2 in fixed relation to the bellows. The same attaching arrangement is provided for each bracket 2 and it will be obviousiparticularly by refer-- ence to Fig. 2 that the bellows attachment may be centralized between the legs of the. rocker by this arrangement and consider able latitude is allowed for chairs of diiien ent' widths and ditierent sizes. As inferred from the foregoing, the bellows consist of.

two compartments 7, 7 and the movable plates 8 and '8 are employed to supply air during rocking movement of the chair, and which airyis drawn through the inlet 0on duit-s 9,9 extending through the main plate 5 and into the respective air chambers 7 and 7'. Each inlet opening has a flap valve 10 so as to effectively close this passage when the air is being forced outthrough the discharge conduits 11, 11. The last mentioned conduitspass preferably outwardly of the chair" and vertically to'a point adjacent tothe position occupied by the head of the occupant of the chair and 1 preferably provide the terminal of each conduit with a spray non, zle 12 to mosteliectively deliver the'air' against the face or the occupant of the] chair. v r p 7 As" will be note'd'by reference to Fig. '3,

eaehof the movable plates 8 and 8 hingedly connected to the central r block l3 at, 1e is provided with aroller or caster member at itslower edge, which caster rests'upon the surface of the fioorbeneath the chair and" is maintained normally in contact thereavith by means of the spring l6, 596522.691 at" 7 its opposite ends to the respective movable bellows plates 8 and S v With the foregoing description in View it discharge conduits, Whenyit. is, cool it is desirable that the bellows attachment. beren;
